How to wiring the weak current access control system, how to wiring the access control system Specif

<> "1. How to wire the weak current access control system.

1. Select an 8-core shielded multi-strand twisted pair network cable with more than square meters, connect the card reader and the controller port, and reserve 2 cores for standby, so you don't need to connect it for the time being.

2. Prepare a 1 square 2-core wire, and connect the two ends to the exit button and the controller port respectively.

3. Use a 1 square 2-core power cord, keep the length within 50 meters, if it exceeds 50 meters, choose a square power cord, connect the two ends to the electric lock and controller port, remember that the length of the line should not exceed 100 meters, so that the basic weak current access control system wiring is completed.

If you want the access control system to be more functional and more secure, you can configure the door magnetic, infrared detector, sound and light alarm, fire fighting equipment, etc., as long as you choose the square 2 core wires, they are all connected to the controller port, these devices are not necessary, you can choose not to connect.

Second, what matters should be paid attention to in weak current wiring.

1. Pay attention to the protection of family letters.

When wiring the weak current, the casing should be configured, which can not only protect the weak current and avoid the bite of the mouse, so as to avoid the problem of biting off the tiger, but also have the effect of moisture prevention to avoid the invasion of water vapor and moisture. Therefore, it is necessary to route the wiring from the casing, and the casing can choose PVC pipe, galvanized pipe, etc.

2. Pay attention to grounding.

Weak electricity will also have static electricity and be struck by lightning, so when wiring, it is necessary to take into account the problems of anti-static, lightning protection and anti-bending leakage.

3. Avoid improper operation.

The terminal blocks of weak current should not be plugged and unplugged frequently, which is easy to have the risk of breakage, and at the same time, the controller cannot be easily moved, disassembled, etc., to avoid all unconventional operations.

1. Switch button connection. One end of the two switch buttons is connected to the ground port of the JP1 interface, the switch button 1 is connected to the OP1 port of the JP1 interface, and the switch button 2 is connected to the OP2 port of the JP1 interface.

2. Power wiring. The 6 ports of a power box, the 2 ports NC are connected with the positive and negative poles of the electric lock 1 respectively, the 4 ports +12V are connected with the positive pole + V ports of the power supply in the JP1 interface, and the 5 GND and 6 Push ports of the power supply end are connected with the output ports of the relay LS1 and LS1 respectively'Connect. The other power box 4 ports are discarded with the wide ports of the lap and the wide ports with the JP1 interface, respectively, the relay output ports LS2, LS2'Connect.

3. Electric lock connection. Two electric lock positive and negative poles are connected with the ports of two power supplies respectively, and the electric lock magnetic port is connected to the JP1 interface GND port, and the electric lock door port is connected with the JP1 interface door magnetic port MC1, MC2 respectively.

4. Connect the card reader. The wiring of the two card readers is the same, which is connected to the +V, GND, Data0, and Data1 ports in the JP2 and JP3 interfaces, including two power cables and two W26 data cables.

5. Communicator connection. The GND+ port of the communicator is connected with the ground port GND, RS485 communication negative, and RS485 communication positive interface in the JP4 interface, respectively.

6. Doorbell wiring. The doorbell is mainly connected to the BPA and BPB ports of the JP5 interface.

7. This completes the wiring.

Access control is complicated, but it's actually quite simple.

Different manufacturers have slightly different wiring and wiring methods, but they are always the same. The digital access control system uses a network cable to simulate the access control system 4* or more lines. It means the wire diameter, and the distance is no problem.

If it is far away, increase the wire diameter, two of the 4 cores are signals, and two cores are power supplies. The door opening button is to send a short-circuit signal to the control board, and after the control board receives the signal, the power is off or energized, (the magnetic lock is to open the door when the power is off).

The network line is a digital access control system. Go to the web.

It is a bus system that takes the bus system.

Not the same product.

There are also different ways of data transmission and how they work.

The wiring method of the access control system is as follows:

1.The positive 12V and GND termination on the access control host are connected to the positive 12V and GND end of the access control power supply;

2.The positive end of the electric lock is connected to the NO or NC end of the access control power supply, and it is usually connected to the NC end. The negative termination of the electronically controlled lock is connected to the GND end of the access control power supply;

3.The push end on the access control host is connected to the push end of the access control power supply. The door opening signal on the access control host is NO, NC, usually connected to the NO end to the push end of the access control power supply;

4.If the other end is connected to the door button, the two wires of the door button are connected to the door button end and the GND end of the access control host, or the push end and the GND end of the access control power supply;

5.If the other end is connected to the card reader, the card reader is connected to the corresponding signal end of the access control host.

The positive termination of the electric lock is connected to the NO or NC end of the access control power supply (depending on the normally open lock and normally closed lock); Usually connected to the NC terminal (power on unlocking, power off lock). The negative termination of the electronically controlled lock is connected to the GND end of the access control power supply;

The push end (door opening signal) on the access control host is connected to the push end of the access control power supply. The door opening signal on the access control host is NO, NC, usually connected to the NO end to the push end of the access control power supply;

If the other end is connected to the door button, the 2 wires of the door button are connected to the door button end and the GND end of the access control host;

In the case of wiring of the access control system, this should be a problem that developers need to consider. Because he will have it done when the house is in your hands.
